Best Quality Calcium Aluminate Cement With Price List
The raw materials of calcium aluminate cement CA-70/80 are high purity calcium materials and high pure alumina. The raw materials should be mixed according to suitable ratio. The raw material should be burned to partly fuse. After cooling, α-Al2O3 powder added into clinker, then ground to cement. The content of Al2O3 is usually controlled within 68% to 72%. The principal compounds of it are CA and CA2.
